java security update

CentOS Errata and Security Advisory CESA-2014:0408

The java-1.6.0-openjdk packages provide the OpenJDK 6 Java Runtime
Environment and the OpenJDK 6 Java Software Development Kit.

An input validation flaw was discovered in the medialib library in the 2D
component. A specially crafted image could trigger Java Virtual Machine
memory corruption when processed. A remote attacker, or an untrusted Java
application or applet, could possibly use this flaw to execute arbitrary
code with the privileges of the user running the Java Virtual Machine.
(CVE-2014-0429)

Multiple flaws were discovered in the Hotspot and 2D components in OpenJDK.
An untrusted Java application or applet could use these flaws to trigger
Java Virtual Machine memory corruption and possibly bypass Java sandbox
restrictions. (CVE-2014-0456, CVE-2014-2397, CVE-2014-2421)

Multiple improper permission check issues were discovered in the Libraries
component in OpenJDK. An untrusted Java application or applet could use
these flaws to bypass Java sandbox restrictions. (CVE-2014-0457,
CVE-2014-0461)

Multiple improper permission check issues were discovered in the AWT,
JAX-WS, JAXB, Libraries, and Sound components in OpenJDK. An untrusted Java
application or applet could use these flaws to bypass certain Java sandbox
restrictions. (CVE-2014-2412, CVE-2014-0451, CVE-2014-0458, CVE-2014-2423,
CVE-2014-0452, CVE-2014-2414, CVE-2014-0446, CVE-2014-2427)

Multiple flaws were identified in the Java Naming and Directory Interface
(JNDI) DNS client. These flaws could make it easier for a remote attacker
to perform DNS spoofing attacks. (CVE-2014-0460)

It was discovered that the JAXP component did not properly prevent access
to arbitrary files when a SecurityManager was present. This flaw could
cause a Java application using JAXP to leak sensitive information, or
affect application availability. (CVE-2014-2403)

It was discovered that the Security component in OpenJDK could leak some
timing information when performing PKCS#1 unpadding. This could possibly
lead to the disclosure of some information that was meant to be protected
by encryption. (CVE-2014-0453)

It was discovered that the fix for CVE-2013-5797 did not properly resolve
input sanitization flaws in javadoc. When javadoc documentation was
generated from an untrusted Java source code and hosted on a domain not
controlled by the code author, these issues could make it easier to perform
cross-site scripting (XSS) attacks. (CVE-2014-2398)

An insecure temporary file use flaw was found in the way the unpack200
utility created log files. A local attacker could possibly use this flaw to
perform a symbolic link attack and overwrite arbitrary files with the
privileges of the user running unpack200. (CVE-2014-1876)

This update also fixes the following bug:

• The OpenJDK update to IcedTea version 1.13 introduced a regression
  related to the handling of the jdk_version_info variable. This variable was
  not properly zeroed out before being passed to the Java Virtual Machine,
  resulting in a memory leak in the java.lang.ref.Finalizer class.
  This update fixes this issue, and memory leaks no longer occur.
  (BZ#1085373)

All users of java-1.6.0-openjdk are advised to upgrade to these updated
packages, which resolve these issues. All running instances of OpenJDK Java
must be restarted for the update to take effect.
